2 Claims. (01. 194 92) This invention relates to a multiple coin attachment for coin controlled locks-for increasing the number of coins necessary to efiect operation of the lock. Dime checking" cabinets and locks of the nature shown in Patent No. 1,640,605, dated August 30, 192?, for example, are constructed to require the insertion of a dime for releasing the lock for'movement from the unlocked to the locked position. The object of the present invention is to provide an attachment whereby two or more dimes will be required to e'flect such releasing of the lock.

The attachment comprises a coin receiving magazine secured to the coin receiver of the lock in position to receive coins therefrom, and

v v I 2 Fig. 10 is asect iohalview through the coin receiver constructed to "operate 'with a single coin as in said Patent No. 1,640,605.

means associated with the magazine and lock 7 is provided for retaining a predetermined plurality of coins in the magazine and receiver with the top coin in 'position to effect the usual releasing of the look when a coin is present. Other cooperating means is provided for releasing the coins from the magazine and receiver when the lock is released and rotated to a predetermined position. The production-of a novel combination of this nature for the purpose described comprises a furtherobject of the invention.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings, "in which:

retaining My invention is particularly applicable to coin controlled locks of the nature shown in said Patent .No. 1,640;60 5 and, "for pur oses of description, I have herein disclosed thesame as.

an attachment to the lock shown in this patent. The following described mechanism is common to both this applicationand saidpatent In the drawings, 9 indicates generally a key cylinder equipped with the usual locking tumblers adapted to b'e'manipulated by a key H, which in the type of lock illustrated serves as an identifying check by which the customer may recover" or obtain access to the belongings which he has deposited in a parcel locker;

Thekey cylinder is provided near :its outer end with a locking bolt [2. adapted to be moved with the cylinder from the unlockedposition shown in Fig. 5 to the locked position shown in Fig. 1. A fragment of the front plate of the locker cabinet frame is shown in Fig. 1, and indicated by reference character [3. The front plate Id of the lock proper is disposed over an opening in the plate 13, its'lower end being provided with a lip l5 engaging the inner face of the plate l3 and its up er end being equipped with a lock H5, by which the plate l4 'a'nd'the parts assembled thereon are detachably located 1 in position in the cabinet. A recorder I! may be connected tothe lock so as to be operated by each actuation of the lock, and whereby the number of lock actuations, and consequently the number of coins deposited, is recorded.

The front plate [4 is provided beneath the key cylinder with a coin slot l8, through which a coin may be inserted e'dgewise into the coin receiver [9 at the back of the plate. As shown in Fig. 10 and in said pate nt,"the coin'is retained in this receiver, as will be'explained, until the lock has been movedlto locked -p osition,-whereupon the coin will be released and permitted to drop into a coin box or coin chute 21'.

Upon a screw stud-or pin 3'2 there is pivotally mounted a locking member, comprising a projection 33, to which the upper end of a spring 30 is attached; an arm 34 provided at its lower end with a finger 35, adapted to project into the coin receiver l9 through'an opening 36in the rear wall thereof; and an'arm iii-equipped at its upper end with a tooth 38, adapted to'engage ina notch 39, formed in the perimeter of a plate ll carried by and forming a part ofth'e liey'cylinderflil. The cylinder, when the lock is in unlocked position,

is disposed in the position shown in Fig. 5, with the tooth 38 just above the notch 39. When the cylinder is turned in a clockwise direction, in an endeavor to lock the lock, this tooth rides into the notch 35 and locks the cylinder against rotation, as will be apparent from an inspection of Fig. 6.

The arm 31 is normally urged in a clockwise direction about its fulcrum 32 by the spring 30, which is connected at its lower end at 42 to a stationary member 43 of the lock casing. This action takes place, however, only in the event that no coin is present in the receiver l9, when the finger 35 is permitted to enter the receiver, as illustrated in Fig. 6. The coin receiver illustrated in Fig. 10 and in said patent is constructed to operate upon the insertion of a single coin 44. If the coin 44 has been deposited in the receiver through the slot l8 prior to turning the key cylinder, this coin will prevent the entrance of the finger 35 into the receiver, thereby preventing the tooth 38 from entering the notch 89, with the result that th key cylinder is free to turn to fully locked position..

The coin is retained in the receiver H! by a.

coin-retaining means comprising the tail 45 of a lever 48, also fulcrumed upon the stud 32, this tall being adapted to enter the receiver through an aperture 41 in the rearwall thereof. The upper end of a spring 24 is attached to a lateral extension 48 of this lever, whereby the lever is urged in a clockwise direction about its fulcrum.

The upper arm 49 of the lever is adapted to engag the perimeter of the cylinder plate 4 I, which is shaped to provide a cam depression into which the arm 49 falls when the lock is in unlocked position, as shown in Figs. 5-and 6. When,

however, the cylinder has been turned in a clockwise direction nearly to completely locked position, the high portion of the cam will engage the arm 49, swinging the lever in a counter-clockwise direction to withdraw the finger 45 from the coin receiver, thereby permitting the coin to drop from the receiver into the coin box beneath, this position of the parts being shown in Fig. '7 of the drawings. Upon return movement of the key cylinder to unlocked position, the finger 45 will again enter the receiver in position to hoid the next coin deposited therein until the lock approaches fully locked position.

The operation of the above described mechanism. with the single coin receiver shown in Fig. 10, is briefly as follows. Assuming the parts to be in the unlocked position illustrated in Fig. 5, if attempt be made to turn the key cylinder in a clockwise direction without previously depositing a coin in the receiver, locking movement of the lock will be prevented by the entrance of the tooth 38 into the notch 39. If, however, a coin has been deposited in the receiver through the slot i8, such coin will prevent entrance of the finger into the slot, and consequently the entrance of the tooth 38 into the notch 39; the key cylinder is therefore free toturn to locked position. As the lock approaches locked position, the lever 46 will be rocked in a counter-clockwise direction. withdrawing the tail from the receiver so as to permit the discharge of the coin therefrom into the coin box. Upon unlocking movement of the lock, the parts are all restored to the normal position previously described.

The object of the present invention is to provide a relatively simple attachment for the above descrifid single coin lock which w ll convert it into a lock requiring two or more coins to efiect the operations heretofore requiring but a single coin.

The attachment comprising the invention embodies a coin receiving magazine 60 constructed to be secured to the coin receiver I9 by means of two screws 62 and 64 extending through holes 66 in the magazine and threaded into the coin receiver. As thus attached the magazine is disposed to receive coins thereinto from the receiver [9. The magazine is furthermore properly located and secured by two fingers 68 integral therewith and extending into two holes 10 in the receiver. Also, as illustrated in Figs. 3 and 4, one wall of the receiver is cut away at 12 to widen the coin slot suiflciently to permit the inserted coin to passthe coin retainer 45 and drop downwardly into the magazine. The magazine is recessed at 14 to receive the retainer 45 therethrough.

Pivoted to the screw 82 is a lever having a coin retaining arm 16 provided with a. coin engaging finger I8 on its free end. An arm also integral with the lever extends outwardly to the recess 14. When the lever is in the position of Fig. 3 the arm 80 is disposed beneath the recess 14 and projecting of the retainer 45 through the recess and above the arm prevents upward pivotal movement of the arm and lever. .In this position of the lever, the finger I8 is in the coin retaining position of Fig. 3 and the uppermost coin is held in position to be contacted by the finger 35. When the retainer 45 is retracted the lever is free to pivot upwardly and release the coins. The operation is the same asalready above described except that a plurality of coins is required to effect operation of the lock.

It will be understood that considerable sums are invested in the thousands of single coin controlled locks in present use and the employment of my invention for the purpose of increasing the number of coins required to operate the look, when and if such increase becomes necessary, eliminates the discarding of these locks and the very substantial loss thatsuch action would entail.

Having thus disclosed my invention what I claim as new and desire to secure by Letters Patent is:

1. In a coin controlled lock having a rotary key cylinder, a coin receiver, a cylinder locking member comprising a portion adapted to enter said receiver and a portion adapted'to lockingly engage said cylinder, means for yieldingly urging said member into locking position, the presence of a coin in predetermined position in said receiver being adapted to render said member inoperative, means for retaining a coin in said predetermined position in the receiver, and means cooperating with the last named means for releasing the coin when the cylinder lock is disengaged and the cylinder is rotated to a predetermined position; an attachment comprising the combination of a coin receiving magazine adapted to be attached to said coin receiver in position to receive coins therefrom, and mechanism associated with the magazine and adapted to cooperate with the coin retaining means for retaining a plurality of coins in the magazine and receiver with the top coin in said predetermined position in the receiver, movement of said coin retaining means to coin releasing position being operative through said mechanism to release said coins from the magazine and receiver.

2. The attachment defined in claim 1 in which said mechanism comprises a pivoted lever having a coin retaining arm adapted to be in position to retain said plurality of coins when said coin retaining means is in coin retaining position and a. second arm for engaging the coin retaining means and holding the first-named arm in coin retaining position when the coin retaining means 5 is in coin retaining position.
